The similarities in composition and structure of protoplasm, enzymes, hormones, DNA, blood etc indicates that:

Options

A. Organisms did not share ancestors in recent past
B. Organisms did not share ancestors in distant past
C. Organisms have shared ancestors in recent or distant past
D. Organisms never shared ancestors

Answer

To answer the question regarding the similarities in composition and structure of protoplasm, enzymes, hormones, DNA, blood, etc., we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Protoplasm and Its Components**:
- Protoplasm is the living substance within a cell, which includes cytoplasm and nucleoplasm. It contains various biomolecules like enzymes, hormones, and DNA.
- The composition and structure of these components are similar across different organisms.

2. **Analyzing the Similarities**:
- The similarities in the composition of protoplasm, enzymes, hormones, and DNA suggest that these components have a common origin.
- For example, DNA is the genetic material in all living organisms, indicating that they share a fundamental biochemical basis.

3. **Considering Evolutionary Relationships**:
- The presence of similar biochemical structures across diverse organisms points towards a shared ancestry.
- This means that all living organisms have evolved from common ancestors, which is a key concept in evolutionary biology.

4. **Evaluating the Given Options**:
- **Option 1**: Organisms did not share an ancestor in the recent past. (False)
- **Option 2**: Organisms did not share an ancestor in the recent past. (False)
- **Option 3**: Organisms have shared ancestors in recent and distant past. (True)
- **Option 4**: Organisms never shared an ancestor. (False)
- Based on the analysis, the correct option is that organisms have shared ancestors in both recent and distant past.

5. **Conclusion**:
- The similarities in the composition and structure of biological molecules indicate that all living organisms share common ancestors. This supports the theory of evolution and the idea of a common biochemical foundation for life.

### Final Answer:
The similarities in composition and structure of protoplasm, enzymes, hormones, DNA, blood, etc., indicate that organisms have shared ancestors in recent and distant past.
